    Abstract
    This paper is about search of photos in photo databases of agencies which sell photos over the Internet. The problem is far from the behavior of photo databases managed by librarians and also far from the corpora generally used for research purposes. The descriptions use mainly single words and it is well known that it is not the best way to have a good search. This increases the problem of semantic ambiguity. This problem of semantic ambiguity is crucial for cross-language querying. On the other hand, users are not aware of documentation techniques and use generally very simple queries but want to get precise answers. This paper gives the experience gained in a 3 year use (2006-2008) of a cross-language access to several of the main international commercial photo databases. The languages used were French, English, and German.

    Abstract
    Language barrier is the major problem that people face in searching for, retrieving, and understanding multilingual collections on the Internet. This paper deals with query translation and document translation in a Chinese-English information retrieval system called MTIR. Bilingual dictionary and monolingual corpus-based approaches are adopted to select suitable tranlated query terms. A machine transliteration algorithm is introduced to resolve proper name searching. We consider several design issues for document translation, including which material is translated, what roles the HTML tags play in translation, what the tradeoff is between the speed performance and the translation performance, and what from the translated result is presented in. About 100.000 Web pages translated in the last 4 months of 1997 are used for quantitative study of online and real-time Web page translation

    Abstract
    The Web has become a large repository of documents (or pages) written in many different languages. In this context, traditional information retrieval (IR) techniques cannot be used whenever the user query and the documents being retrieved are in different languages. To address this problem, new cross-language information retrieval (CLIR) techniques have been proposed. In this work, we describe a method for cross-language retrieval of medical information. This method combines query terms and related medical concepts obtained automatically through a categorization procedure. The medical concepts are used to create a linguistic abstraction that allows retrieval of information in a language-independent way, minimizing linguistic problems such as polysemy. To evaluate our method, we carried out experiments using the OHSUMED test collection, whose documents are written in English, with queries expressed in Portuguese, Spanish, and French. The results indicate that our cross-language retrieval method is as effective as a standard vector space model algorithm operating on queries and documents in the same language. Further, our results are better than previous results in the literature.

    Abstract
    Das Hauptthema dieser Tagung - Multimedia - beschäftigt sich mit der Vielfalt der Medien und Quellen, mit denen wir es heute zu tun haben. Da liegt es nahe, sich auch mit einer anderen Form der Vielfalt, dem Thema Mehrsprachigkeit zu beschäftigen. Und die Veranstalter dieser Tagung waren der Meinung, dass ein Schweizer dazu mit Sicherheit etwas zu sagen habe. Das ist insofern richtig, als wir in einem mehrsprachigen Land leben und mit diesem Problem im Alltag vertraut sind, sowohl im täglichen Leben, wie auch eben im dokumentarischen Alltag. Aus dieser praktischen Sicht und nicht als Sprachwissenschafter, der ich nicht bin, möchte ich mich dem Thema nähern. Die Vielfalt der deutschen Sprache: Wenn die Schweiz ein mehrsprachiges Land ist - ist dann Deutschland im Gegensatz dazu ein einsprachiges Land? Auf den ersten Blick sicher ja - in Deutschland spricht man deutsch - aber die Sache ist doch nicht so einfach. Natürlich leben auch hier, wie überall, Menschen aus anderen Ländern mit anderen Muttersprachen - in dieser Optik gibt es wohl fast nur mehrsprachige Länder. Aber auch wenn wir nur die einheimische Bevölkerung mit deutschem Pass betrachten, ist die Sache nicht so eindeutig. Zwar haben sie das Deutsche als gemeinsame Sprache, die von allen gesprochen und verstanden wird. Aber die eigentliche Muttersprache der Deutschen oder mindestens einer grossen Mehrheit ist nicht das Hochdeutsche, sondern einer der vielen Dialekte. Diese Dialekte sind ja höchst unterschiedlich und einem Bayern oder Schwaben geht es sicher nicht anders, als es mir vor Jahren ergangen ist, als ich in Norddeutschland erstmals plattdeutsch sprechen hörte: ich hab nicht mal mehr Bahnhof verstanden und benötigte einige Wochen, bis ich der Unterhaltung wenigstens in groben Zügen folgen konnte. Das Hochdeutsche ist da der gemeinsame Nenner und ermöglichst erst die Verständigung, auch wenn es mit vielfältigen Akzenten und regional eingefärbtem Vokabular gesprochen wird. In diesem Sinne ist die Situation nicht anders als in der deutschsprachigen Schweiz, wo auch ganz unterschiedliche Dialekte gesprochen werden. Allerdings gibt es doch einen wichtigen Unterschied: Hier in Deutschland ist Hochdeutsch die allgemeine Umgangssprache sowohl in der mündlichen wie in der schriftlichen Kommunikation. Dialekte werden im privaten Bereich gesprochen, aber im öffentlichen Bereich, im Geschäftsleben, in der Wissenschaft etc. ist Hochdeutsch die Umgangssprache.

    Abstract
    For the sake of national security, very large volumes of data and information are generated and gathered daily. Much of this data and information is written in different languages, stored in different locations, and may be seemingly unconnected. Crosslingual semantic interoperability is a major challenge to generate an overview of this disparate data and information so that it can be analyzed, shared, searched, and summarized. The recent terrorist attacks and the tragic events of September 11, 2001 have prompted increased attention an national security and criminal analysis. Many Asian countries and cities, such as Japan, Taiwan, and Singapore, have been advised that they may become the next targets of terrorist attacks. Semantic interoperability has been a focus in digital library research. Traditional information retrieval (IR) approaches normally require a document to share some common keywords with the query. Generating the associations for the related terms between the two term spaces of users and documents is an important issue. The problem can be viewed as the creation of a thesaurus. Apart from this, terrorists and criminals may communicate through letters, e-mails, and faxes in languages other than English. The translation ambiguity significantly exacerbates the retrieval problem. The problem is expanded to crosslingual semantic interoperability. In this paper, we focus an the English/Chinese crosslingual semantic interoperability problem. However, the developed techniques are not limited to English and Chinese languages but can be applied to many other languages. English and Chinese are popular languages in the Asian region. Much information about national security or crime is communicated in these languages. An efficient automatically generated thesaurus between these languages is important to crosslingual information retrieval between English and Chinese languages. To facilitate crosslingual information retrieval, a corpus-based approach uses the term co-occurrence statistics in parallel or comparable corpora to construct a statistical translation model to cross the language boundary. In this paper, the text based approach to align English/Chinese Hong Kong Police press release documents from the Web is first presented. We also introduce an algorithmic approach to generate a robust knowledge base based an statistical correlation analysis of the semantics (knowledge) embedded in the bilingual press release corpus. The research output consisted of a thesaurus-like, semantic network knowledge base, which can aid in semanticsbased crosslingual information management and retrieval.

    Abstract
    With the recent rapid diffusion over the international computer networks of world-wide distributed document bases, the question of multilingual access and multilingual information retrieval is becoming increasingly relevant. We briefly discuss just some of the issues that must be addressed in order to implement a multilingual interface for a Digital Library system and describe our own approach to this problem.

    Abstract
    Das Problem der mehrsprachigen Suche gewinnt in der letzten Zeit immer mehr an Bedeutung, da viele nützliche Fachinformationen in der Welt in verschiedenen Sprachen publiziert werden. RSWBPlus ist eine bibliographische Datenbank zum Nachweis der Fachliteratur im Bereich Planen und Bauen, welche deutsch- und englischsprachige Metadaten-Einträge enthält. Bis vor Kurzem war es problematisch Einträge zu finden, deren Sprache sich von der Anfragesprache unterschied. Zum Beispiel fand man auf deutschsprachige Anfragen nur deutschsprachige Einträge, obwohl die Datenbank auch potenziell nützliche englischsprachige Einträge enthielt. Um das Problem zu lösen, wurde nach einer Untersuchung bestehender Ansätze, die RSWBPlus weiterentwickelt, um eine mehrsprachige (sprachübergreifende) Suche zu unterstützen, welche unter Einbeziehung eines zweisprachigen begriffbasierten Thesaurus erfolgt. Der Thesaurus wurde aus bereits bestehenden Thesauri automatisch gebildet. Die Einträge der Quell-Thesauri wurden in SKOS-Format (Simple Knowledge Organisation System) umgewandelt, automatisch miteinander vereinigt und schließlich in einen Ziel-Thesaurus eingespielt, der ebenfalls in SKOS geführt wird. Für den Zugriff zum Ziel-Thesaurus werden Apache Jena und MS SQL Server verwendet. Bei der mehrsprachigen Suche werden Terme der Anfrage durch entsprechende Übersetzungen und Synonyme in Deutsch und Englisch erweitert. Die Erweiterung der Suchterme kann sowohl in der Laufzeit, als auch halbautomatisch erfolgen. Das verbesserte Recherchesystem kann insbesondere deutschsprachigen Benutzern helfen, relevante englischsprachige Einträge zu finden. Die Verwendung vom SKOS erhöht die Interoperabilität der Thesauri, vereinfacht das Bilden des Ziel-Thesaurus und den Zugriff zu seinen Einträgen.

    Abstract
    With increasing moves towards an integrated Europe the need for multilingual access to information becomes more pressing. One aspect of this need which has largely been neglected is the provision of multilingual access to OPACs and this paper is concerned with exploring this problem area. The need for multilingual OPAC search capabilities and the difficulties associated with this are discussed. The problems of subject access in particular are highlighted. Research into subject searching in monolingual OPACs is reviewed and its relevance to multilingual OPACs is outlined. Given the limitations of current machine translation of natural language it is likely that the utilisation of controlled subject search facilities. Finally some possible directions for further research are considered

    Abstract
    With the introduction of the single market, more and more European Community information databases are becoming available either online or on CD-ROM. Some databases are full text but many are bibliographic. Users may access them free text or through controlled descriptors but ideally they should be able to search through 1 or more subject access points. Each of the databases uses a different method and the different subject access methods, employing thesauri or classification schemes, are examined. Proposes a solution to the problem of multiple thesauri and multilingualism

    Abstract
    Subject-based retrieval in distributed resources is a current problem in online searches for bibliographic references. Building portals to similar resources is only the ferst step, the subsequent navigation via different search interfaces presents certain difficulties. To make retrieval easier it is necessary to adapt these different resources. Potential approaches (standardisation as opposed to "cross-walks") and methods (automated as opposed to intellectual effort) will be discussed. This includes a Brief appraisal of the future of work with multilingual terminology: - The "classical" approach (Multilingual Thesauri), - The "Internet" approach (linking) Recent developments in mono- and multilingual environments will be presented (MACS, CARMEN, Economics Crosswalk).

    Abstract
    In line with the international flavour of the book, Patrice Landry looks at the multilingual problem. This chapter is mainly concerned with a review of MACS (Multilingual Access to Subjects); a project with the strategy of developing a Web-based link and search interface through which equivalents between three Subject Heading Languages can be created and maintained, and by which users can access online databases in the language of their choice. The three systems in the project are German, French and English language. With the dramatic spread of use of the Web, particularly in the Far East, such projects are going to be increasingly valuable and important.

    This paper presents the problem statement, the methodology and the preliminary results of a research project aiming to compare two different approaches for indexing images, namely: traditional image indexing with the use of controlled vocabularies, and free image indexing using uncontrolled vocabulary. The experiment intends to measure their respective performance for image retrieval in a multilingual context, in terms of effectiveness, efficiency, and satisfaction of the user.
